Output liquid nitrogen step of Panchao liquid nitrogen tank and Panchao liquid nitrogen tank use precautions
Output liquid nitrogen step of Panchao liquid nitrogen tank
1. The first step is to close the vent valve
2. The second step is to open the booster valve
3. In the third step, carefully observe the pressure gauge and proceed to the next step when it rises to a certain value of 0.05 MPa (0.5 kg/cm2).
4. In the fourth step, the drain valve is opened for continuous infusion.
Panchao liquid nitrogen tank use precautions
1. The first liquid filling of the Panchao liquid nitrogen tank should be pre-cooled with liquid medium and then slowly filled.
2. When the PanChao liquid nitrogen tank to store the liquid medium, be sure to close the inlet/discharge valve and the pressure increasing valve, and the vent valve must be opened.
3. When the PanChao liquid nitrogen tank to transport the liquid nitrogen medium, it must be ensured that the switching state of each valve should be the same as that during storage, and it must be ensured that it will not shake during transportation.
4. When transporting liquid nitrogen, please use the transport tank. It is forbidden to use the storage tank as the transport tank.
5. The vacuum nozzle on the liquid nitrogen tank, the seal of the safety valve, the seal can not be damaged.
6. It is strictly forbidden to place objects on the container lid and seal the neck.
7. If the liquid nitrogen tank is not used for a long time, please discharge and dry the liquid medium inside the tank, then close all the valves.
8. It should be handled gently when using it. When opening each valve, the force should be moderate and not too fast.
9. liquid nitrogen is a kind of ultra-low temperature liquid (-196 ° C), if it splashes on the skin, it will be frostbite. Pay special attention when filling the liquid nitrogen tank and taking out liquid nitrogen.
